This Summer I had to replace my fuel pump in my truck, the gas gauge was out and the engine started losing acceleration. So, I did the research and figured out how to
change it out. It is a simple process of removing the truck bed and the pump, and I have a video I will share that I made on youtube here.
In short, all you need to do is remove the truck bed, which is just a few large bolts, disconnect the gas cap hose from the bed and lift the bed back and out of the way. Then swapping out the pump is a cinch. Watch my video and you can see how easy it is. You can grab a pump for the GMC pick up here: Fuel Pump for Silverado & Sierra 1500
